Estadio Monumental José Fierro, Football stadium in San Miguel de Tucumán, Argentina

The Estadio Monumental José Fierro is a football stadium with concrete stands, partially covered seating sections, and a natural grass pitch at its center. The venue has undergone expansions over time to accommodate growing crowds and modern sporting needs.

Designed by Spanish architect José Graña, the stadium was completed in 1922 with a capacity of 5,000 and inaugurated on 21 May 1922 with a 1–1 friendly between Atlético Tucumán and Racing Club. Originally called "Grand Stadium", it was renamed in 1938 after José Fierro, the club's president and founding member. It was the first roofed stadium in Tucumán and the first with an upper grandstand.

The stadium's name honours José Fierro, president and founding member of Club Atlético Tucumán, adopted in 1938; the ground was first called "Grand Stadium". Fans of the club, known as Decanos, fill the concrete stands, and the ground also hosts Argentina national rugby union matches, including a 24–16 loss to Scotland in June 2010, Argentina's first defeat there after seven wins.

The stadium sits at the corner of 25 de Mayo and Chile streets in the Villa 9 de Julio neighbourhood. The pitch measures 105 by 70.20 m, and the stands and roof are concrete. Access was expanded in the 2019 Tensolite S.A. works, which added new toilets and entrances alongside 2,600 seats and VIP boxes.

Scotland beat Argentina 24–16 here in June 2010, the Pumas' first defeat at the ground after seven straight wins. France played here in 2012 and 2016, and the Tucumán Rugby Union has faced New Zealand (1991), South Africa (1993 and 2000) and Australia (1997 and 2002).
